Electric Actuator  Structure Diagram Types and Applications of Actuators 1. Basic Concept: An Actuator is a device that accepts the output signal of a regulator to exert influence on the object of regulation

Structural principle of Electric Actuator 1. After the Electric Actuator receives the switching signal from the control system, the motor does not rotate and makes a humming sound
Overview of the internal structure of Electric Actuators: There are three basic types of Electric Actuators: partial rotation (partial rotation), multiple rotation (multiple rotation) and direct stroke (linear).
An electric actuator consists of a power component and a position

An electric actuator usually consis

ts of a reducer, a two-phase servo motor, and a position transmitter. The servo motor adopts a squirrel cage two-phase AC servo motor, which has large starting torque and soft mechanical properties
When an electric actuator is used with a valve, the operating temperature is transmitted to the valve body, and the body temperature increases. When the working medium is high, the bracket connected to the valve plays a role in reducing heat conduction

It is easy to cooperate with the electric adjustment instrument and simple to install and wiring. The disadvantages are complex structure, large volume, small thrust, expensive price, and the average failure rate is higher than that of Pneumatic Actuators

The electric actuator is composed of a motor, a deceleration mechanism, a limiting mechanism, an over-torque protection mechanism and a position feedback device. Electric actuators use a motor as the drive source and DC as the control and feedback signal

The mechanical limit of the linear electric actuator adopts a built-in detent limit structure, which can effectively protect the seat, stem and spool. The adjustment structure produces a certain displacement or angle to directly regulate the flow of the fluid. The electric actuator is an important part of the electric adjustment system

The electric Control Valve consists of an electric actuator and a Control Valve. The working principle is shown in Figure 1
Take the overall proportional adjustment mechanism of the MD series electric actuator as an example

An electric actuator usually consists of a reducer, a two-phase servo motor, and a position transmitter

The invention patent technology relates to the manual and electric conversion structure of the  electric actuator
